The present invention is relative to improvements in spinning machines and it more particularly concerns the properly so .called winding devices.

As a rule, in the spinning machines actually in use and more particularly intended to'the wet spinning of flax and tow, the spindles cooperate with fliers provided with pig-tall ends surrounding the bobbins. On account of the great rotation speed, of these'elements,

the dimensions of the fliers and, consequently, of the cops are necessarily'limited, and, on .the other hand,.the taking down of these fliers for the replacement of the bobbins is a long operation constituting a waste of time.

The present invention aims to increase the efliciency of spinnin machines, on the one hand by'increasing t e dimensions and the diameter of the bobbins, thereby decreasing the frequency of their replacement, on the other hand by rendering the spindles independent from the element playing the part ofthe fliers, so as to avoid the taking down of the fliers or replacements of the cops and, on the other hand, by reducing the dimensions of the mechanisms, so as to increase their number for the same machine and to increase at the same timetheir rotary speed. These objects are obtained, according to the invention, by twisting and guidin the thread by means of pig-tails carri by downward projecting arms, which are given a'rapid rotary movement. These arms are mounted on a rotary ring pierced with a central hole of a slightly greater diameter than that of the cop. On the other hand, the cops are mounted onone or more platqs or rails,

which are given a vertical reciprocating ment of the cops, without any interference whatever of the rota a a The invention is so re ative to the mechanical devices securing the combined movement of the spindle-frame, allowing of stopping the bobbins for there-fastening of broken threads and ensuring the perfect guiding of the threads. The means of carrying the invention into effect depends, in practice, on the kind of spinning machine to whichthei are applied.

In order t at the invention may be easily understood, it will be described hereafter in detail, with reference to the figures of the accompanying drawings, which illustrate, diagrammatically and by way of example, an embodiment of the invention. 1 v a The figures are relative to a machine for the wet spinning of flax.

Withreference to these figures, 1 designates the framework of the machine and 2', the driving drum, 3 being lateral gutters intended to collect the impurities and liquid projections deriving from the yarn. 5 designates the set of delivery rollers receiving the yarn 6 from the feed bobbin 7 and delivering it in a non-twisted state to the thread guide 8. The thread having passed through the thread guide 8, then asses through a separator 9 and is twisted y means of a rotary ring 10 provided with arms 11 suspended from it, said ring'playing the part usually plafyed by the fliers. The rotary ring 10 is pre erably ball mounted on the supporting plate 12 and it is provided with two short downward projecting arms 11 fitted-at their ends with pigtails 13.

The rapid rotary movement of the rings is imparted to them by endless'ropes or cables 14, each of which is wound about the driving drum 2, a tension pulley and two of the rings 10, one located on each side of the spinning machine. The tension pulleys 15 are mounted on a sliding carriage 16 slidably mounted on a bracket of the frame and the position of which is controlled by return springs or tension weights 17 suspended at theend of ropes or chains attached to said sliding'carriage 16. The spindles are mounted on the spindle-carrying plates or rails 18, which generally'support six, eight, ten or more spindles; they are supported by vertical shanks or lifter rods 19. The latter are capable of sliding vertically in' bearings 20 and are given a vertical reciprocating movement combined with a gradual downward movement, the arrangement being such that the plate or rail 18 is lowered of the thickness of the thread after each vertical movement. I a; The spindles receive the cops 21, the diameter.

1%; of which is very slightly smaller than that of the central hole provided inthe rings 10 and than the inner diameter of the separators.

-9,in such a manner that the cops 21 can be engaged in said members and just leave the necessary clearance for the passing of the thread 22 between them.

When placed in their position, the cops 21 are fitted in sockets 23 forming part of a V'- shaped whorl 24 on which frictionally bears the braking cable 25. This cable is tensioned by the'weight 26 and is more or less bent-over the pulley or whorl 24 according to the'hole of the plate 27 in which it has been engaged.

"The rail 18, carrying these devices, is mounted on the upper'port-ion of the lifter rods 19, through the medium of hinged joints 28,'the arrangement being such that the rail can be tipped towards the operator for the purpose of removing the bobbins when the latter have been completely wound and when the device is in its lowermost position.

The mechanism ensuring the above-mew tioned combined movement comprises cams 29 fixed on the cam-shaft of the spinning machine and acting upon double-arm levers 30. The latter support, at their lower portion, the driving mechanism, to which is fastened a belt or chain 32, the end of whichis V wound round a drum 31. To this drum 31 are attached the drums 33 provided with flattened portions 35 and on which is wound the end of the chain or belt 34 supporting the lower portion of the lifter rods 19. It will be understood that the oscillatory movement 0 the double-arm levers is thus transformed into a reciprocating movement of the links 32 and 34 and the corresponding movement of the lifter rods 19. The function of the flat portion 35 of the drums 33 is to reduce the amplitude of said movement when the lifter rods are in their uppermost position, in such a manner as to obtain on the lower portion of the cop a conical base portion, on which will be subsequently wound the different thread la em. The gradual downward movement of the rail 18 and lifter rods 19 is obtained radual unwinding of the link 32, the

bya on the drum 36 supend 0 which is fastened ported by the lower end of the double-arm lever 30.

This drum 36 rotates a'very small angle at every movement of the lever 30. For this purpose, said drum forms part of a helical wheel 37 driven by a worm 38, on the spindle of which is mounted a bevel pinion 39. This pinion is driven by another bevel pinion 49, forming part of a ratchet wheel 41, in the teeth of'which engages a pawl 42. The spindle of this awl 42 is fixed to the framework of the mac line, whilst all the other spindles of the mechanism are carried by the doublearm lever 30.

It will be understood that for every oscillation of the lever 30 the pinion 40 and the wheel 41 rotate about the pivot of said lever and the pawl 42 strikes the wheel 41 and causes it to rotate a peripheral distance corresponding to one tooth, said wheel 41 then causing a slight rotation of the drum 37' and the unwinding of the chain 32 of a uantity, the arrangement being such that t e lifter rods are lowered the thickness of the thread.

The working of the above-described spinning machine will beeasily understood. The

cops having been positioned on the spindles and their ropes 25 suitably tensioned, the plates 18 are brought totheir normal position and the plates 18 and litter rods 19 are completely lifted by actin upon the driving mechanism, by means 0 a key or a W ndlass actuating the ratchet wheel 41. In this position the cop is completely engaged in the ring 10 and the separator 9. The thread is attached at its lower portion and the machlne is started. Through the" action of the flat portion'35, the vertical reciprocating movement of the spindle-frame is started with a reduced amplitude, in such a manner that a conical base portion is formed on the lower part of the cop, on which the thread will be subsequently wound per consecutive COIllCEl" layers. This winding is efiected gradually by much better guided, so that its ballooning is f avoided. The result of this is that the tension, which is ensured by means of the braking action exerted on the cop by the ropes 25, can be strongly reduced, the advantageous movement of result of which is to avoid the excessive tractions on the threads which cause their frequent breaking in the known spinning machines.

On the other hand, in a spinning machine according to the invention, the stopping of the rotary rings for re-fastening the broken threads, etc., is no longer efiected by the hand,

as is the case in the known spinning mafreleather or other appropriate material, allowing of exerting a braking action on the V- shaped rings 10. On the other hand, these rings are provided with a recess 45, in which can engage the finger 46 of a stop lever 47 in such a manner that, after the ring has been stopped by the braking action, the workwoman can maintain it in this position by a catch through the medium of the lever 47 It must be understood that the invention is not restricted to the embodiments described hereabove. The figures of the accompanying drawings show, however, immediately the technical advantages of the invention, more particularly for what concerns the eificiency of the spinning machine and, therefore, the general efliciency of spinning plants.

Indeed, the fact that,according to the invention, the cop only has 'to be engaged in the rings and separators, allows of reducing the diameter of these members, thus of increasing the number of spindles for an equal length of the spinning machine. Moreover,

" as the winding of the cop is effected during its gradual disengagement and that there only is between the arms 11 the conical portion of the cop, the length of these arms can be reduced and their rigidity suitably ensured, this allowing of increasing their speed.

At the same time, this arrangement permits of using copsof great length and of increasing the diameter of the winding of these cops, which considerably increases their capacity. Lastly the tipping movement of the spindle plates or rails facilitates their replacement by suppressing all hindrance due to the presence of the fliers. The safety of the worlnnen is increased by the braking and stopping devices of the rings. The increase ofthe capacity of the bobbins reducing the frequency of their replacement, the suppressing of the operation of taking down the fliers and the tipping of the spindles accelerating this replacement, the suppression of the ballooning of the thread allowing of reducing its tension and decreasing the frequency of the breakings are many factors which very efliciently act upon the working of. the spinning machines and allow the same number of workwomen of surveying a greater number of machines. The new improvements can as well be apning and to the spinning of any kindof materials.

' I claim:

In a spinning machine, in combination: a set of delivery rollers for stretching the yarn, yarn guides, a hollow disc mounted for rotation on a stationary rail of the frame, a pair of short downward projecting arms carrled bysaid disc, the end of one of which receives the yarn coming from the yarn guide; means to rotate said disc and arms at a great speed, a separator formed with and above said stationary rail, a spindle secured to a movable rail, means to impart a vertical to-and-'.

fro movement to said rail, combined with a gradual downward movement, the. arrange.- ment being such that at the beginning of the gradual downward movement the spindle and cop which is mounted thereon are com-.

pletely engaged in the hollow disc and separator, the diameter of the central hole of the disc and of the separator being slightly greater than that of the empty cop, the difference being just great enough to allow the yarn to pass through, the cop being, on the other hand, completely disengaged from the separator, disc and short arms at the end of the gradual downward movement, means to tip the cop at this moment for removin purposes and means to brake the spindle uring spinning, which spindle is not driven to rotate.

In testimony whereof I signed hereunto my name.
